This five-day, hands-on negative workshop is for the experienced collodion ambrotypist or tintypist who wants to get to the next level. Collodion negatives were used in combination with every photographic printing process invented prior to 1880. These include salt, cyanotype, albumen, developed-out salt, gum, carbon, platinum, palladium, photo ceramic, and more.

Taught by Mark Osterman, participants will learn the theory that sets the collodion negative apart from ambrotypes and tintypes. The rare dry collodion process will also be taught, allowing the photographer to shoot negatives in the field without the need for a darkroom or silver bath on location.

The workshop includes shooting, processing, and redeveloping wet plate negatives at the Scully & Osterman Skylight Studio. Dry collodion negatives will be prepared at George Eastman House and exposed on the historic grounds of the museum. Participants will also learn the salt printing process and make a proof from their favorite negative.

Each participant will receive a manual with complete instructions and formulas for both the wet and dry collodion negative written by Mark Osterman and facsimile readings on the topic of collodion negative making. Participants will also view original albumen and salt prints by Julia Margaret Cameron, James Robertson, Gustave le Gray, Eadweard Muybridge, and many others from the George Eastman House collection.

Audience: Limited to five, this five-day program is specifically for those who wish to attain a higher level in their collodion technique. Prior experience in basic collodion ambrotypes or tintypes is strongly suggested.

Tuition: $1,200/$1,100 members, plus $200 materials fee
